I have an NSTableView with a single column that has a custom cell.
During a live resize, I recalculate the row height in the delegate
method -tableView:heightForRow: and return the result. However,
some rows don't grow larger. I presume I need to call the
tableview's -noteHeightOfRowsWithIndexesChanged for each row that
has a height change. Is it okay to call this from within the
tableView:heightForRow: method?
No, it is not; you'll have to redo your logic, or call it with a
range for all rows (probably the easiest thing to do).
Thanks Corbin.
What about from within the tableview delegate method -
tableViewColumnDidResize ?
That is fine; note that it is only sent out when the live-resize
method ends. Your calculation in -heightForRow: can't depend on the -
[tableColumn width], unless you call the -noteHeightXX method more
frequently (ie: you'd have to capture when the setWidth: happens by
subclassing the table column).
